From a financial standpoint I can see the upgrade, but not from a looks standpoint.
Thompson was dating Jordy Craig for a while (see photo below), but it appears that relationship is over because they have wipe each other clean off their IG pages and according to TMZ he has been dating Khloe Kardashian this summer.
Jordy is quite attractive, but who knows what happened.
Flip the pages for more photos of her and video of Tristan & Khloe.
